REGISTER-SLAT OPERATOR.

Specification of Letters Patent. Patgmted Egg '7, 1Q15 Application filed February 16, 1915. Serial No. 8,520.

Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements In Register-Slat Operators, of which the following is a speci fication.

This inventionrelates to register slat operators, and belongs to the class of contrivances intended for use in connection with registers in ventilating and hot air heating systems and apparatus.

The object of this invention is the production of a device for working the slats back and forth, the whole including the slats be ing constructed of sheet metal, and themrious parts having special formation and particular arrangement with regard one to another, wherebymanufacture is materially cheapened and a superior and very durable register is made. I r

The construction and arrangement of the parts of this invention are illustrated in the accompanying drawings, of which Figure 1 represents a slat in its open position, the frame and slide being shown in section. Fig. 2 is a top plan view of the slat alone showing the ear formed at the top thereof and the groove in the ear. Fig. 3 is a cross-section of the slat on the broken line a2a: of Fig. 1, looking in the direction of the arrow. Fig. 41 is a top plan view of the slat in its closed position with relation to Fig. 1 or Fig. 7. Fig. 5 is a cross-section of the slide taken on the broken line zz of Fig. 7. Fig. 6 is a top plan view of the slat in its half closed position with relation to Fig. 7. Fig. 7 isa horizontal section of a portion of the top of the register frame on the broken line g -4 of Fig. 1, showing a top plan View of a portion of the slide.

Throughout the drawings and description the same letter is used to refer to the same part.

Considering the drawings, the slat A, made of sheet metal, has a stiffening groove (4 extending lengthwise. At the top and bottom, the reduced ends of the slat are formed into hollow, cylindrical pintles or pivots B and b which engage suitable spaced holes in inwardly and forwardly turned portions C and c of the frame D of the register. Lying transversely within the frame in front of the pivots and ontop of the slat is a slide E, operated by a fingerpiece e. The slide is movable transversely with respect to the axis of the slat, and rests directly upon the ear that is formed by'turning over an edge portion ofthe slat at right'angles with the plane of the slat. The ear F usually has the form shown in Figs. 2, 3, 1 and 6. The car has an opening or upwardlyopening groove 7. The axis of the groove is at an angle, ordinarily forty-five degrees,

with the plane of the slat, and the axis of the groove if extended would intersect perpendicularly the axis of the slat andthe two axes would lie in one vertical plane.

As shown in Figs. 1, 2, and 4, the outer ends of the grooves f are closed in order that when the parts are assembled as shown in Fig. 1, the tongues G may not slip out at the ends of the grooves.

As best illustrated in Fig. 5 the slide has a tongue projecting downwardly below its bottom, made in practice by stamping out a piece of the bottom of the trough-like slide so that it is held by one end and extends downwardly. The tongue is designated by the letter G and is constructed and arranged to engage the groove f when the parts are assembled as illustrated in Figs. 1 and 7. In Fig. 7 a second slat H is shown, and any desired number of slats may be employed.

In explaining the operation of this invention, let it be borne in mind that in Figs. 1 and 7 the slats are shown in their open positions. The open position of the slat alone is illustrated in Fig. 2. In Fig. 7 it will be noted that the tongue G is nearthe outer end of the groove f. That is to say, when the slats are open the tongue is at the outer end of the groove. Suppose now movement is made to close the slats. Such a movement would result from pressing the fingerpiece e in Fig. 7 toward the slat A. When half-way closed, each slat will assume the position illustrated in Fig. 6, and it will be understood that the groove 7 will then be ar ranged beneath the slide directly across it. Consequently the tongue G is no longer at the outer end of the groove 7'', but, by the movement of the groove andiits own movement it now occupies a position intermediate between the ends of the groove. The closend of the groove are once more brought to- 1.

ing movement continuing, the groove takes.

gether. The closed position of the slat is shown in Fig. 4. The movements opening the slats simply reverse the movements just described.

Having now explained the construction and operation of this invention, what I claim and desire to secure by Letters Patent of the United States is In a register slat operator, the combination with a sheet metal frame having the rear portions of its top and bottom turned in wardly and forwardly and provided with spaced holes, of slats having pivots at their ends engaging the said holes, each of the said slats having a portion projecting horizontally from its top edge to form an ear, and the said ear having a groove extending IVILLIAM T.
